At present, laptop case is generally adopt aluminium base as base material, then processing and manufacturing is carried out through anodic oxidation, etching and incrustation successively, wherein in etching work procedure, because the reason of this step itself will produce a large amount of contaminated liquid, cost for wastewater treatment like this is very high, and seriously limits the addressing of laptop case Workplace, improves cost of transportation.
In view of this, the present inventor, for the above-mentioned difficulties further investigation of prior art when production laptop case, has this case to produce then.
Summary of the invention
The object of the present invention is to provide a kind of moulding process of laptop case, it revolutionizes traditional processing and manufacturing mode, not only solves in prior art and there is with serious pollution problem, but also has the low feature of production cost.
In order to reach above-mentioned purpose, solution of the present invention is:
The object of the present invention is to provide a kind of moulding process of laptop case, wherein, comprising:
1. the pretreatment of sheet-metal layers: make sheet-metal layers successively through cleaning, passivation and oven dry three process;
2. gluing: toward the sheet-metal layers upper surface gluing after drying;
3. printing film is gone up: by printing the film of pattern with identical speed, utilize roller to cover on the upper surface of sheet-metal layers;
4. compound: utilize upper and lower roller sheet-metal layers, glue and printing film three to be pressed together.
5. subsequent treatment: the composite material after compound is good carries out punching, shaping and trimming, to form laptop case finished product.
Further, this matting is cleaned by the cleaning equipment that sheet-metal layers is arranged side by side by three roads successively.
Further, this step 2. middle glue adopted is hot melt adhesive film, this hot melt adhesive film is web-like and covers the upper surface of sheet-metal layers with identical speed, and 4. this step is then carry out composition operation under the temperature range of 180 DEG C to 220 DEG C, and this step subsequent treatment 5. also comprises the step of cooling.
After adopting said structure, the moulding process of a kind of laptop case that the present invention relates to, it adopts the mode of ink printing and gummed to instead of the technology of conventional anodization and etching, thus make can not produce metal pollutant in the process of shaping laptop case, solve the problem of contaminated wastewater from root, the present invention simultaneously also has the low effect of production cost by the way.Especially adopt the mode of hot melt adhesive film, not only solve the problem of glue waste liquor contamination, and due to any glue can not be wasted, therefore also greatly reduce production cost.

Detailed description of the invention
In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
As shown in Figure 1, a kind of laptop case 100 that the present invention relates to, comprise thin layer 1, printed layers 2, composite layer 3 and sheet-metal layers 4, this thin layer 1, printed layers 2, composite layer 3 and sheet-metal layers 4 from top to bottom set gradually and are bonded together by composite layer 3.
In order to protect product surface for processing procedure or when dispatching from the factory, this laptop case 100 also comprises the diaphragm 5 being positioned at thin layer 1 upper end.In addition, can also be formed with back side processing layer 6 in the lower end of sheet-metal layers 4, this back side processing layer 6 carries out respective handling according to actual conditions, can be such as layer of paint, or for realizing the functional layer of the functions such as anticorrosion, antirust or conduction.
In the specific implementation, this sheet-metal layers 4 can be selected from the one in aluminium sheet, almag plate, cold rolling carbon steel thin plate, galvanized steel plain sheet or Stainless Steel plate, and this thin layer 1 adopts pet layer.
As shown in Figure 2, the present invention also provides a kind of moulding process of laptop case 100, comprises the steps:
1. the pretreatment of sheet-metal layers 4: make sheet-metal layers 4 successively through cleaning, passivation and oven dry three process; Particularly, in the present embodiment, this sheet-metal layers 4 in web-like, and adopts charging gear outwards to carry; This matting is then for clean the cleaning equipment that sheet-metal layers 4 is arranged side by side by three roads successively, and passivation is then preferably positive and negative passivation simultaneously.
2. gluing: toward the sheet-metal layers 4 upper surface gluing after drying; The mode of its gluing can adopt traditional glue groove and roller gluing, and namely the mode of gravure realizes; But more preferably, please refer to shown in Fig. 3, in the present embodiment, the contaminated wastewater caused when the glue in glue groove does not use also can also save glue simultaneously, this glue adopts hot melt adhesive film 7, this hot melt adhesive film 7 is web-like and covers the upper surface of sheet-metal layers 4 with identical speed, and specifically it is guided by a guide roller 71.In addition, also please refer to shown in Fig. 4, it adopts solvent-based thermal melten gel to coat on sheet-metal layers 4, this solvent-based thermal melten gel is positioned at black groove 91, this drop roller 92 is immersed in black groove 91 and also can be transferred on sheet-metal layers 4 by glue spreader 93 by solvent-based thermal colloidal sol, finally be coated with solvent-based thermal colloidal sol and can form glue-line on sheet-metal layers 4 after oven heat 94, be namely equivalent to the hot melt adhesive film 7 in Fig. 3.
